Package with barrier wall and method for manufacturing the same

摘要

A ball grid array (BGA) package that may suppress flash contamination may include a flash contamination barrier wall. The barrier wall may be a portion of a copper pattern provided on a substrate. During a molding process, the flash contamination barrier may prevent a flash from contaminating a ball land. The barrier wall may restrict the flash to flow through a concave portion that may be defined by a surface of the substrate.
